See https://github.com/FStarLang/steel/blob/nik_dice/share/steel/examples/pulse/bug-reports/UnificationVariableEscapes.fst

Also weirdness there with how pulse reports errors and its interaction with expect_failure

There are two parts to the fix:

in the commit referenced above, I fixed an issue where we were not descending into a host_term to substitute uvar solutions. So, that fixes the main issue.
Additionally, the weirdness with error reporting and expect_failure: This is fixed with @mtzguido 's help in an F* branch, specifically this commit: FStarLang/FStar@c33c383
